What type of wave can actually reach Earth's inner core
kenny6666 [7]
I believe body waves can actually reach the core as they follow raypaths refracted by the varying density and modulus of Earths interior.

Hope this helps!

How many moles of co2 are found in a 168.2 gram sample
andrew11 [14]

Answer:

Number of moles = 3.82 mol

Explanation:

Given data:

Number of moles of CO₂ = ?

Mass of CO₂ = 168.2 g

Solution:

Number of moles = mass/molar mass

Molar mass of CO₂ = 44 g/mol

By putting values,

Number of moles = 168.2 g/ 44 g/mol

Number of moles = 3.82 mol

The density of the fat tristearin is 0.95 g cm−3 . Calculate the change in molar Gibbs energy of tristearin when a deep-sea crea
KatRina [158]

The formula for the change in Gibbs energy of a solid is:

ΔG = Vm ΔP

where, ΔG is change in Gibbs, Vm is molar volume, ΔP is change in pressure

ΔP = P(final) – P(initial)

P(final) = 1 atm = 101325 Pa

P(initial) = ρ_water *g *h = (1030 kg/m^3) * 9.8 m/s^2 * 2000 m = 20188000 kg m/s^2 = 20188000 Pa

Vm = (950 kg/m^3) * (1000 mol / 891.48 kg) = 1065.64 mol/m^3

 

So,

ΔG = (1065.64 mol/m^3) * (101325 Pa - 20188000 Pa)

<span>ΔG = -21405164347 J = -21.4 GJ</span>

A separatory funnel contains the two immiscible liquids water and toluene. Use the given densities to determine which layer is o
damaskus [11]

Answer:

  • Top layer Toluene
  • Bottom layer Water

Explanation:

When two non-miscible liquids are put together, the one with the higher density will be on the bottom, while the one with the lower density will be on top.

Meaning that in this problem's case toluene would be on the top layer and water in the bottom layer.
